Abstract
(EN)
A light guide plate for guiding light from a light source to form an image in space is provided with a light introduction unit and a light-emitting unit. Light from the light source is incident on the light introduction unit. The light-emitting unit includes a curved exit surface which emits the light from the light source incident on the light introduction unit, and is curved to connect to the light introduction unit.
